FAQ
How do I trigger a HTTP Request action from Google Calendar?
Most workflows in this list use either a Google Calendar webhook trigger (real-time) or a polling trigger (every N minutes). From there, downstream HTTP Request nodes handle the action. Open any workflow's detail page to see the exact node graph.
Do I need both a Google Calendar and a HTTP Request account?
Yes — n8n connects to each integration via your own credentials. AutomationFlows strips credential IDs before publishing, so you'll add your own.
